Answer:
Step-by-step explanation:
One number would be
9.31
The 3 in this number is 3/10
The 3 in the given number is 3/100
3/10 is 10 times bigger than 3/100
3/10 = 0.3
3/100 = 0.03
0.03 * x = 0.3 Divide both sides by 0.03
0.03/0.03 x = 0.3/0.03
x = 10
$540
Explanation:
7.5% of 1800 is 135
135 • 4 = 540
Answer:
The volume of the figure is 905 cubic units.
Step-by-step explanation:
Rotation is a method of solid transformation which involve turning a given line, or object about a reference point. In the given question, rotating segment AB completely about the y-axis would form a 3 dimensional figure of a sphere.
volume of a sphere = 


where r is the radius of the sphere.
Given that AB = 6, then the radius of the sphere = 6
volume of sphere =
x
x 
=
x 216
= 905.14
volume of sphere = 905 cubic units
The volume of the figure is 905 cubic units.
